IMPROVEMENT IN BOB-SLEIGH.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, LEVI F. SKINNER, of the town of Springvale, in the county of Fond du Lac, and in the State of Wisconsin, have invented certain new and useful Improvements, in Sleigh-Bobs; and I do hereby declare-that the following is a full, clear, and exact description thereof, reference being had'to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure l is a plan view.

Figure 2 is a side elevation.

Figure 3 shows the groove in the under side of one of the runners.

The nature of my invention consists in making each runner movable, and independent in its own moth the manner of binding together the front ends of the rear bobs by the forked iron, having its centre point attached to the reach, and the groove in the runner or runners, as hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the constructionof my invention, in fig. 1, A the runners, a the hubs, B the axles connecting the runners, O the slide-bearing of the reach, D the reach connecting both pair of bobs, E the forked connecting-iron, for connecting the runner of the rear set of bobs, F the rear set of hounds, G the guide-pole, II the front hounds, Z? the elastic catch, with bolt through the reach-pole, to which may be attached the double-tree, to which the power may be applied.

In fig. 2 the same letters as in fig. 1 designate like parts of the invention. old 02 dd 11 the spokes, set into the hubs a, and the other ends set into the runners A. The hub and spokes are the segment of a wheel, differing only in the irregular length of the spokes, which are made to reach the runner at various distances from the centre of the hub. 12 c the brace or knee-braces, to which is attached, by bolt and eye, the cross-bar g, to which the guide-pole G is fastened. e the brace attached to the axle B and bearing 0, to support the same. The runners, by means of the hubs a a, may be attached to the axles in any of the known ways of attaching wheels to axles. The forked iron E is fastened to the reach by means of an eye on the under side of the reach, through which the point passes, and in which it can move back and forward, the rear ends being attached to the front ends of the runners.

In the operation of my invention, the bobs beingmade to move independently of each other, as each runner may turn on its own axle, it will be seen that if the runner should strike against any obstruction in the read, each runner can accommodate itself to it, and be made to rise over it, having only to lift one-fourth of the weight of the load, instead of the one-half of the load, as in other bobs not thus constructed. And in case one of the runners is broken, I can easily detach the same from the axle, not having to take apart any framing, as is now required in repairing bobs. I

It will be seen that the fork-iron E is so constructed that the front end, which passes through the eye 1 in fig. 2, is so made that it will slide to and fro suflieiently far to accommodate any size required in-the runner, rising to pass over any obstruction in its way. The gutter or groove in fig. 3 is for the purpose of preventing the bobs from sloping sideways, and two of the runners may be grooved, if found desirable to do so.

It will further be seen that the bearing of the perch or guide-pole is fastened to the bob by means of the kneebraces c e, and has its bearing in the rear of where the runners are curved, to assist in backing the bobs. As the pressure in backing is on the plane of the runner, it cannot rise up in the rear in backing, which is the case in bobs with the perch-pole attached above or on the curve of the runner.

By my invention I am able to make a strong and easily-running set of bobs, and easily repaired if required.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is-- The hubs a a an, spokes d oldd, forming the segment of a wheel, when attached to runners A A A A, in combination with axles B B, constructed as described, and operating as set forth.

In testimony that I claim the above-described invention I have hereunto signed my name this 28th day of February, 1867.
